' ill/'1 ATTO EY Patented Sept. 10, 1935 *llumrap STATES PATENT OFFICE tThis invention rela'tes generally to book rests, and "particularly" to adjustable supports which "permita'book, paper or other reading matter to be held securely and properly-and 'atthe desired iiiangle and'height for properre'ading.

A further object of the'invention' isto provide abook holder combined with'me'ans for the ac- 'commcdationlotpencilsg pens;crayons, books and ''other such material-as may be utilized in writing, 'reading,tdrawing=, -etc; the device being so con struct'ed'as to properly' house-and retain such ma- ==terla1stsecurely when the stand is either in set- .up or in collapsed positions.

A further object of the invention'is to provide a book support 'featuredby' means for maintaining the 'same -in one position 'o'f-adjustme'nt and at the same time aifording means for the support of a' book or packet of papers.

A still further object'-of' the invention-is to provide improved and simplified means whereby the ang'ularity' of the reading surface of the book may be quickly and easily varied so as to assume the proper angle for reading or studying.

A further object is to provide a book support which shall be of simple and inexpensive construction, which involves the use of but few simple and readily assembled parts, which has its parts so constructed and organized as to minimize the opportunity for wear or breakage, and which will prove highly efficient in accomplishing the purposes for which it is desired.

With these objects in view, together with others which will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts, all as will be described more fully hereinafter and particularly pointed out in the claims.

In the drawing:-

Fig. 1 is a perspective view of a book support constructed in accordance with the invention,

Fig. 2 is a longitudinal sectional view taken through the improved support,

Fig. 3 is an enlarged transverse sectional view taken through the support,

Fig. 4 is a fragmentary sectional view taken through the support and the extensible member and illustrating the manner in which these parts are slidably connected,

Fig. 5 is a detail perspective view illustrating the manner of securing the book rests to the extensible member, and

Fig. 6 is an enlarged sectional view taken substantially upon line 66 of Fig. 3.

Referring now more particularly to the drawing, I represents generally a base member formed preferably of relatively thin'sheet metal, of rectangular shape and having upstanding lateral and end walls 8. This base is in theform of a relatively shallow tray, and has rubberpadsor suction cups 9 secured to its underiace in order 5 that it may be firmly and yet movably rested upon a surface such as a desk or table.

Hinged at one end as at In within the upstanding side walls 8 of the base is the support member I I, in the form of a rectangular metallic l0 plate having its lateral edges I2 turned inwardly or downwardly as shown; the said downwardly turned flanges being pivoted at one end between the said side walls as disclosed. This support has its flanges provided with openings, recesses or 15 notches I3, which notches extend inwardly into the body of the support'to provide rests I4.

The support is provided with an extensible member indicated at I5, this member in the present instance taking the formof a yoke mem- 20 ber of L construction. This yokeis of a width 'to properly fit between downwardly extending flanges I2 of the support, and portions of these flanges are deflected so as to provide retaining members I6 to hold the yoke properly assembled 25 within or beneath the support. By assembling the yoke or extension member in this manner, it is apparent that the operative length of the support may be increased or diminished depending upon the degree of adjustment of the yoke.

This yoke is provided at each side and near its inner end with book supporting arms or brackets I'I. Each bracket is in the form of a tubular bar or arm having its ends deflected at right angles in opposite directions. One of these 35 deflected ends is rotatably supported within a barrel portion I8, formed in the arm of the yoke member, in such manner that the arm or bracket is capable of being swung in an arc of greater than These arms are of such gauge as to 40 snugly engage within the recesses I3 and the rests I4.

With the support and yoke arranged in the manner described, it is apparent that when the arms are swung to downward or rearward position, the yoke member may be slid longitudinally of the support. When the arms are moved outwardly or forwardly into the openings or recesses I3 and rests I4, it is obvious that these arms will hold the support and yoke against movement 50 relative to each other, and at the same time the said arms provide adequate support for the lower end of a book or sheaf of papers resting upon the support.

In order that the support may be properly held 55 in angular positions a bail i9 is provided. This bail has its ends pivoted as at 20 within the upstanding side walls 8 of the base, and its bight portion 2| is adapted to engage behind any one of a series of lugs or stops 22 provided in longitudinal series upon the rear or underface of the support II. The bail is so pivoted as to be capable of swinging downwardly upon the floor within the upstanding walls of the base I so that the support and the extension therefor may fold or swing within the base and have its upper surface disposed substantially flush with the upper edges of the walls 8. By reason of the particular manner of mounting the arms or brackets H, the same may be swung rearwardly or inwardly upon their pivots to the rear face of the support H so as not to interfere with the proper collapsing of the support member.

From the foregoing, it is apparent that I have provided a book rest of simple and inexpensive construction and yet which will prove highly satisfactory in practice. By providing more or less of the lugs or stops 22 the angularity of the book support may be minutely regulated. The peculiar mounting of the arms enables them to serve the double function as to angle and height of book.

While the foregoing is a description of the preferred embodiment of the invention, it is to be understood that I am not restricted to the precise details as disclosed, as variations in such combination and arrangement may be resorted to within the spirit of the invention as defined by the claims.

Having thus described my invention, I claim:-

1. In a book rest, a support having spaced openings, an extension member slidable on support, and a bracket hinged to said member capable of swinging into any one of said openings to hold the support and member against relative movement.

2. In a book rest, a support having spaced openings in one edge, an extension member slidable on said support, a bracket hinged at one end to said member, said bracket capable of swinging into any one of said openings to hold the support and member against relative movement.

3. In a book rest, a support having spaced openings in one edge, an extension member slidable beneath said support, a bracket hinged at one end to said member adjacent said edge, said bracket of substantially the same breadth as said openings and capable of fitting into the same.

4. In a book rest, a support having notches in its lateral edges, an extension member slidable on said support, a bracket hinged at each side of said member, said brackets capable of swinging into said notches and projecting forwardly from said support to hold the support and member against relative movement.

5. In a book rest, a support having notches in its lateral edges, an extension member slidable upon said support, retaining flanges on said support holding said member in sliding position, notches in said flanges, and arms hinged to the lateral edges of said member capable of swinging into or out of said notches.

6. In a book rest, a support, flanges projecting inwardly from the lateral edges of said support and comprising guides, an extension member having its edges engaged in said guides so as to slide therein, said flanges having spaced notches extending into the face of said support, and arms hinged to extension member and engageable in said notches.

7. In a book rest, a support having notches in its edges, an extension member slidable upon said support, arms hinged to said member and movable into said notches to hold said member against movement upon said support.
